My invention relates'to a device for-cleaning matrices of type-setting machines, and

y it 'is an object of my. inventionto provide a device of "the kindIdescribedinwhich the matrices are cleaned on several sides during a single'operati'on andcontact offcleaned faces with uncleanediones'is'avoided. It is also an,object of "my invention to provide means for. positively feeding the matrices in the proper position, past the brushes which clean them, and z to so construct and arrange said" brushes'that they give the matrices'a good polislr'and' that their; life is increased: I

It is very important: that" the matrices shouldbe suitably guided on their way past the brushes. Heretofore theinatrices'avere fe'd past-"the brushes by 'means oflc-onveyer belts. Iii my device there isp-provided-a feedin dii'sc havingpairsof 'lugs on opposite si es which" are: adapted, toengageprojections onpthe sides ofthematrices and thus preventiedgingof the matrices in eitherdirection 'of""rotation:-j I

The sharp edges of the matrices ca-use considerable wear to the brushes, and therefore some of the brushes are made adjustable;

It iS nQtenoughto. remove the dirt from the "matrices; it isals'o important that the brushes should impart to them a certain degree of polish so that they keep tight durlng the casting operation and donot stick in the channels of the supply hoppers.

I impart this fine polish by means of brushes the bristles of which are of very thin brass wire. Preferably such bristles are made rather long and the brushes themselves make up for wear, so as to increase their life to the maximum.

A further advantage ofmy machine resides in that it is possible to repeatedly circulate through the machine the matrices to be cleaned, so that the cleaning operation can be repeated as often as required if the mat rices are not in the desired condition after the first circulation. v

In the drawings afiixed to this specification and forming part thereof a device embodyin my invention is illustrated diagrammatical y by way of example. In the drawings:

Fig. 1 is an elevation,

Fig. 2 is a plan view, of my device and Figs. 3 and 4 are sections on the lines AB and CD of Fig. 2, respectively.

Referring now to the drawings a is a verthis purpose;

tical channel secured-oaths frame F of th'e device through which the matrices M are insertedas they come-from the type-sett ing machine. g 'is *disc .secu-red on" a shaftg" which isrotatablycarried lin the frame 'F andgfis a crank for rotating said-shaft.

Obviously" other aneans may be -provided for l p andg are -pulleys-keyed to the "Shaftig; The pulley g is: connected'with a pulley :1

by a belt or cord; and'pulleyris keyed ona at the front-end ofithie'framwFz carewlugs on the belt 6, which belt may be of steel; and

"(l are laminated I springs-z which allow: only the lowermostmatrice from the pile in cthe channel a tor-pass alongwith-the belt J).- V

c. is a horizontal brush extendaingaboveand i parallel to: thte beItQb, 70;: is an: inclined :brush I andc'z' is-ea strip of emeryzclotlr' whichzextends alongiitsiotherisidenl '1 V f A is i a .arcsilient I b3lClgBi connecting the :coni 'veyo-i Z) lwlllllfltllfi surface: of the 1 disc =gnwl1ere the matrices; area'engaged iby lugs lcifland-fed past clrcular brushes Z to a second bridges and an e]ector 1) which is rotated from the pulley p on the shaft 9. The brushes Z are secured to a steel hoop 0 which is held in the frame F at 0 and 0". connected to said hoop 0 by screws n and the hoop is adjusted by means of a right and with the channel a at its front end.

The operation of my improved device is as follows The matrices inserted in the channel a are successively engaged by the lugs c of the belt I) to whichmotion is imparted by rotating the crank 9' and carried to the disc 9 past the bridge On their way the matrices are cleaned and polished on the upper face by the brush 6 at one edge by the inclined brush it and at the other by the strip z' to which the matrices are held at some pressure by the brush h. Each matrix that has passed the bridge f is engaged by a pair of lugs 70 on the disc g and carried along with said disc past the brushes Z which act on the lower faces of the matrices. Finally the The brushes are p matrices move past the bridge 7" and the ejector v to the horizontal passage m from which they may be removed or, if it is desired to subject them to further cleaning, they may be returned to the channel a and the belt 6.

I claim 1. A device for cleaning matrices of typesetting machines comprising a frame, a channel on said frame for guiding sa'id matrices, a belt of steel at the base of said channel, a shaft carried in said frame and operatively connected with said belt, means for rotating said shaft, a disc on said shaft adapted to receive the matrices, brushes distributed along said belt and said disc and adapted to act on said matrices as they are fed past said brushes, and a channel connected with said disc at one end and said feeding channel at the other.

2. A device for cleaning matrices'of typesetting machines, oomprising a frame, a channel on said frame, for guiding said matrices, a belt of steel at the base of said channel, a shaft carried in said frame and ,operatively connected with said belt, means for rotating said shaft, a disc on said shaft adapted to receive the matrices, an inclined brush extending along one edge of said belt, a strip of grinding material extending along its opposite edge, a brush extending over the upper surface of said belt and the matrices on said belt, brushes distributed along said disc and adapted to act on said matrices as they are fed past said brushes, and a channel connected with said disc at one end and said feeding channel at the other.

3. A device for cleaning matrices of type-- setting machines, comprising a frame, a channel on said frame for guiding said matrices, a belt of steel at the base of said channel, a shaft carried in said frame and operatively connected with said belt, means for rotating said shaft, a disc on said shaft adapted to receive the matrices, an inclined brush extending along one edge of said belt, a strip of grinding material extending along its opposite edge, a brush extending over the upper surface of said belt and the matrices on said belt, brushes distributed around said disc and adapted to act on said matrices as they are fed past said brushes, means for adjusting said last named brushes, and a channel connected with said disc at one end and with said feeding channel at the other.

4. A device for cleaning matrices of type setting machines comprising a frame, a channel on said frame for guiding saidj matrices, a belt of steel at the base of said channel. a shaft carried in said frame and operatively connected with said belt, means for rotating said shaft, a disc on said shaft adapted to receive the matrices, lugs for positively engaging said matrices on said belt and said disc, the lugs on said disc being arranged in pairs }on opposite sides thereof, brushes distributed along said belt and said disc and adapted to act on said matrices as they are fed past said brushes, and a channel connected with said disc at one end and with said feeding channel at the other.

In testimony whereof I affix my signature.
